A) \[I>{{I}_{0}},\,\,V<{{V}_{0}}\]
B) \[I>{{I}_{0}},\,\,V={{V}_{0}}\]
C) \[I={{I}_{0}},\,\,V<{{V}_{0}}\]
D) \[I<{{I}_{0}},\,\,V={{V}_{0}}\]
Correct Answer: A
Solution :
[a] On connecting voltmeter, equivalent resistance of the circuit decreases. Therefore, current in circuit increases \[(I>{{I}_{0}})\]. \[\therefore \] Potential drop across ammeter + Potential drop across R = E.M.F. of cell. In second case due to increase in current through ammeter, potential drop across ammeter increases. Hence potential drop across R decreases.You need to login to perform this action.
